BACKGROUND In order to facilitate normal gait, toes require to be in a rectus position during the propulsive phase. This requires a correct balance and sequence of activity of the intrinsic musculature of the feet. Alteration of this balance and sequence may lead to the development of claw toes. Atrophy of the lumbricals occurs in the development of claw toes, but it is not known if changes occ...

Introduction: Postoperative finger function after flexor tendon graft is occasionally unsatisfactory. Postoperative adhesion inhibits the restoration of excursion and strength of the grafted tendons. Hyaluronic acid (HA) is not only a lubricant but also a factor to prevent adhesion. The purpose of this study is to evaluate the changes of excursion resistance between potential graft donor source...

Intratendinous ruptures of a flexor digitorum profundus tendon are rare in patients who do not have rheumatoid arthritis. A case of a patient with no history of autoimmune disease who suffered a traumatic rupture of the flexor digitorum profundus tendon to the ring finger in the mid-palm is reported.

BACKGROUND In recent years, distal nerve transfers have become a valid tool for nerve reconstruction. Though grafts remain the gold standard for proximal median nerve injuries, a new distal transfer of flexor carpi ulnaris branches of the ulnar nerve to selectively restore anterior interosseous nerve function, concomitant with median nerve graft repair, could enhance outcomes. The objective of ...

Understanding muscle architecture of the foot may assist in the design of surgical procedures such as tendon transfer, biomechanical modeling of the foot, prosthesis design, and analysis of foot function. Flexor digitorum brevis (FDB) is the most superficial intrinsic muscle of the sole of the foot. When compared to the little finger, the little toe has less function and opposition is absent in...

In light of the interplay among physiological finger tremors, this study was undertaken to investigate the transfer effect of fatigue on coordinative strategies of multiple fingers. Fourteen volunteers performed prolonged position tracking with a loaded middle finger while measures of neuromuscular function, including electromyographic activities of the extensor digitorum (ED)/flexor digitorum ...

Oscillatory activity in the primate motor cortex has been shown to be phase locked to oscillations in contralateral hand and forearm muscle activity in the 15-30 Hz frequency range. Recent studies have shown that the degree of coupling between the cortex and the periphery is strongly influenced by the type and degree of movements of the digits. It has also been suggested that changes in cortico...
